Do you know the level of understanding of your audience? That would drive the level and complexity of the questions, based on where they 'should' be on camshaft knowledge. For example is this for - novices, intermediates, experts, professionals? It may span more than one, but unlikely all. This would then help build out how low or high the conversation will start and then finish.

Explain why different cams with very similar lift and duration numbers need different springs, seat pressure, spring rate, etc. What advantage or disadvantage is found comparing cams which require more or less spring pressure or spring rate. Describe the effect on HP and Torque of cams which require more or less pressure/rate.

The way people rise above the level of novice is through exposure to expert knowledge and to engage in conversation with people deemed to be expert.

Just spitballin’ here mike , but in my experiance, I would start with the rationale (what you see as important, your approach) for how you pick cams. You need to be yourself!

Make a list of what you think the important points of picking cams are and I would bet the common mistakes you want to cover will become appearant fast.

Sorry that you already know all of this -but the point I guess that I am trying to make is that if this talk is a face to face class type of situation-be authentic by being yourself and giving your honest assessments. The students will want that or they will just be thinking “same Thing as everywhere else” (at least that is how it goes with my HS industrial technology students) - hopefully the people you are talking to won’t take as much convincing as the teenagers lol-

How will higher lift affect where the engine makes power?(or does it?) Everything else left the same.It may give gains in output but does it affect where the engine previously made hp. As does duration? And if heads peak flow at say .700 is there any gains designing cam for .750-.800 lift? I wouldn't mind knowing the answers to those questions Mike.
